Regulatory Assets and Liabilities
Regulatory Assets and Liabilities	Note 9. Regulatory Assets and Liabilities During 2011, the CPUC issued a decision regarding the $34.2 million of litigation proceeds previously received by Cal Water during 2008 which is being used to replace infrastructure damaged by the gasoline additive Methyl tert-butyl ether (MTBE). The decision requires use of these proceeds for costs incurred as a result of MTBE contamination with any related benefits to be provided to Cal Water customers. Such usage includes transfer of the amount to contributions in aid of construction (CIAC) for remediation or replacement project costs once complete. Usage of the proceeds is reported to the CPUC through an Advice Letter or General Rate Case filing. As of December 31, 2012, $22.4 million of the proceeds was recorded as CIAC. Cal Water used $0.8 million of the net proceeds to replace damaged infrastructure during the third quarter of 2013. The remaining balance of $9.8 million at September 30, 2013 is included in regulatory and other liabilities. During 2011, Cal Water added balancing accounts for its pension plans and conservation program. Both balancing account effective dates were January 1, 2011. The pension plans balancing account is a two-way balancing account that tracks the differences between actual expenses and adopted rate recovery which will result in either a regulatory asset or liability. The conservation program is a one-way balancing account that tracks the differences between actual expenses and adopted rate recovery which may result in a regulatory liability if actual conservation expenses are less than adopted over the three year period ending December 31, 2013. As of September 30, 2013 and December 31, 2012, the pension balancing account was a regulatory asset of $2.3 million and $2.4 million, respectively. The conservation balancing account was a regulatory liability of $7.7 million and $6.5 million as of September 30, 2013 and December 31, 2012, respectively.
